Sometimes, its colder than a deep freeze out there… but that's not going to stop you from manning a blind waiting for a giant Alberta Whitetail during the mid-November rut. For when you have to be stationary or on the move in twenty below, you'll really appreciate our three layer (400 grams of Thinsulate™ Ultra insulation) removable liner combined with 3mm wool felt, and our rubber bottom sandwiched with another 600 grams of Thinsulate™ and 9mm of wool felt underfoot. The Northern features our famous K-Talon™ outsole with an open tread pattern, deep relief and specialized "K" lugs for multidimensional traction. These boots allow you to stand on frozen tundra all day long when others are trapped inside only dreaming of adventure. 5.8 lbs. The Kenetrek K-Talon™ outsole is protected under US Patent #D580,637. Made in Thailand.
